Outer Face Plate

After Googling several sites, and browsing through many forum posts, I came across a comment how someone was using there router on low speed to make clean cuts through polycarbonate without splintering or cracking the material.

Dimensions as per diagram earlier match the Inner Faceplate; ideally I should have cut and drilled both Face plates @ the same time, but I took the hard path although I still managed to get them to match.
